Causes of Car Power Window Malfunction

POWER WINDOW 
MALFUNCTION
WHAT IS A CAR POWER WINDOW?
Car Power Windows work using a button or lever that is 
positioned on the door panel. Power window faults, like many 
other issues pertaining to automobiles, are not very prevalent 
but can occur with little to no prior warning. Because their 
motors and window regulators — which control the windows 
up and down movement — are utilized the most, the front 
driver-side windows are the ones most likely to malfunction. 
However, it has the potential to affect not just the windows 
but also the power roofs. This can happen even in newer 
automobiles. 
CAUSES OF CAR POWER WINDOW 
MALFUNCTION
1. Wiring Issue
It is possible for the sequence of wires that connect a power 
window switch to a window motor to become damaged, which 
would result in a power window becoming unable to move.
It usually happens when repairing another component in a 
power window, which may affect the wiring of the power 
window. Hence, it is always advised to take your vehicle to a 
professional for windshield repair or replacement.

2. Window Regulator
A window regulator is a mechanism that allows windows to be 
adjusted vertically. Windows without regulators cannot be 
adjusted. Every power window has its own individual regulator 
for the window.
In the event that a window's regulator has been broken, it will 
no longer be possible to move a window simply by pressing a 
button. A malfunctioned power window can even affect the 
safety of your vehicle. Anybody can access your vehicle 
through an open or partially open window. Also, if it's down, 
there's a chance you won't be able to raise it back up.

3. Window Motor
Another common problem that occurs in power windows is due 
to window motor. A power window's window motor is 
responsible for delivering electrical energy to the window 
regulator, which subsequently makes the window move up and 
down.
When there is an issue with the window motor, no electrical 
energy is available to move the window. This prevents the 
window from being opened or closed.
4. The Power Toggle
The power switch can become worn out to the point that it no 
longer functions correctly. It often happens due to rough touch, 
which affects the movement of power windows. Hence, it is 
essential to see that the power switch works properly at all 
times.
